7 Claims.

This invention relates to filing devices and more particularly to animproved fastener, and holders whereby such fasteners and materialsecured thereby can `be detachably held in suitv `able folders and thelike. This application is a division of my (zo-pending application Ser.No. 520,788 filed March '7, 1931 and a continuation in part of myco-pending application Ser. No. 381,368 filed July 26, 1929.

Fasteners for papers, documentsand similar material having prongs whichpass through suitable perforations in such material and engage acompressor or locking device to securely bind the material are now in4common use. When such fasteners are used to hold the material in afolder, the prongs pass through perforations in the folder or suitableholders are secured to the folder to engage and hold the fastener.

It is the object of the present invention to provide an improvedfastener which is adapted to be fastened to a folder or back, and animproved holder whereby the fastener may be secured detachably to thefolder or similar support.

Other objects and advantages of the invention will be apparent as it is,better understood by reference to `the following specification andaccompanying drawings, in which Fig. l is a view in perspective of theimproved fastener;

Referring to the drawings, 5 indicates the base of a fastener havingprongs 6 which are adapted to pass through perforations in the papers orother material to be secured. The prongs may also engage perforations 7in a com- February pressor 8 which is adapted to rest upon the `ma;-terial above the fastener. When the prongs 6 Vare bent over thecompressor, the material is securely bound. The compressor may beprovided with locking means such as ythe slides 9 which en- 60 gage theprongs after they are bent, thereby binding the material in the fastenermore securely. Y

The base 5 is provided with two upwardly projecting spaced lugs 10struck preferably Vfrom 65 the metal forming the base. The 4lugs arevpreferably pointed so that they will easily 'pass through evenrelatively stiff material. One function of the lugs is to `permitsecuring the base to any suitable material forming a back or folder. .70Thus, for example, if the fastener is to :be mounted on a back ofrelatively stiff material such as lcardor press-board, the prongs 6 andlugs v10 can be driven through the back by means of a lsuitableapparatus such as that described in my co-pending application aboveidentified. The lugs l0 are clinched to secure 4the fasteners in place.4

This machine (Figs. 3, 4, 5 and 6) comprises a base 11 and a pivoted arml2 having a head A13. The head carries a pivoted guide 14 with spaced 30clips 15 which are resiliently held 4by a spring l5 adapted to receiveone of lthe fasteners with the prongs G and lugs l0 depending. A dieplate 16 lon the base has openings -17 to receive the prongs. A pair ofpins 18 on thehead engage openings 19 in the base 5 of the fastener andhold it in proper position `until it is released. A cam plate 20 on theguide 14 engages .theA die plate i6 when the head descends and the guidethen swings rearwardly to clear the fastener.

When a sheet of any suitable material 20 is placed on the die plate andthe head is caused lto descend, the prongs 46 and lugs 10 are vforcedthrough the material and the lugs are bent Tby engagement with the dieplate to securely hold the 95 fastener in place. The head isthen liftedand when another fastener has been inserted is ready for the succeedingoperation.

The lugs l0 serve another function in connection with the holders whichcan be secured to a back or folder to permit detachable connection of afastener and the material carried thereby. In Figs. 8 and 9, such aholder is shown on a back 21 to which it is secured by rivets or otherf105 fastening means. The holder comprises a plate 22 with a portion 23thereof struck up from the body thereof. It may be of metal or any othersuitable material. The portion v23 which is rasied slightly above thelevel of the back to Which -110 it is applied has oppositely disposednotches 24 and 25 and preferably a rounded corner 26.

The base 5 of the fastener is slipped under the portion 23 of the holderwith one of the lugs 10 engaging the notch 25. By swinging the base ofthe fastener the opposite lug 10 can be brought into engagement with thenotch 24 and the fastener. By moving the base in a longitudinaldirection the fastener is secured until released. The lugs l0 may bebent slightly to overlie the portion 23. If the fastener is secured to aback, the portion 23 is slipped between the base 5 and the back and thelatter is thus secured by the holder.

In the device as shown in Fig. 10, the holder 26 is secured to a back 27as in the preceding embodiment and is provided with a portion 28 raisedslightly above the back. It is provided with a notch 29 and a roundededge 30. The fastener is slipped under the portion 28'with one vof thelugs 10 in the notch and the other engaging the rounded edge.

In Fig. 11 of the drawings, the holder 31 is secured to a back 32 as inthe preceding embodiments and is provided with a raised portion 33 Withdepressed lips 34. The base 5 of the fastener is slipped under theportion 33. The lips 34 engage the edge of the base 5 and hold it inposition from which it can, however, be released readily when desired.

The fastener and holder as described provide a simple and effectivearrangement for detachably securing files 0f papers and the like onbacks 4or on folders. The fastener may also be secured directly to aback or in a folder, and the apparatus described permits the applicationof the fastener to any suitable support to which it is secured by thelugs. These lugs serve to secure the fastener permanently to the supportor back and also cooperate with a holder or similar support or back orin a binder.

The devices as described are inexpensive and can be applied to a varietyof filing equipment affording a safe and satisfactory binding means forletters, documents and other papers or material in sheet form.

Various changes can be made in the details of construction andarrangement of the parts without departing from the invention orsacrificing any of the advantages thereof.

1. A holder for sheet fasteners comprising a base adapted to be securedto a support and an offset portion raised above the surface of the baseportion at one edge thereof and having a notch extendingrinwardly fromone end adapted to engage and hold a fastener.

2. A holder for sheet fasteners comprising a base adapted to be securedto a support and an offset portion raised above the surface of the baseportion and having notches extending inwardly from opposite ends adaptedto engage and hold a fastener.

3. A holder for sheet fasteners comprising a base adapted to be securedto a support and an offset portion raised above the surface of the baseportion, said offset portion being split lengthwise at its ends with theouter split portion of each end being depressed to form a fastenerengaging and holding lip.
